Problems solved by technology

For example, removing uninteresting footage from within shots taken during a holiday can be a time-consuming process.
Currently, video editing systems do not provide any form of high level segmentation, but are based on extraction of key frames from the footage based on color histograms and motion detection.

Embodiment Construction

[0044]FIG. 1 shows a method of finding SISs in footage (specifically in a single “shot”, defined in this document as the footage between one switching “on” of the camera and the next switching “off” of the camera). First of all we check whether the footage we are searching for SISs was shot with a handheld camera held or if it was tripod mounted [101]. A method for performing step [101] is shown in FIG. 2 and is explained below. If camera was tripod mounted then there are no SISs by definition and no further searching for SISs is done (Output “No” from box 101) (step [102]).

[0045]If the footage was taken with a handheld camera (output “Yes” from box 101). then we calculate (step [103]) the ‘Speed of Camera Motion’ and ‘Direction of Camera Motion’ (Dir) for each frame of the footage. A method for performing step [103] is shown in FIG. 3 and is explained below.

[0046]Now for each frame in the footage, we take absolute difference of Dir, from Dir of previous frame (DeltaDir) (step [104]...

Abstract

Segments of interest within video footage are identified automatically. Such segments of interest include portions of the footage which were taken using a hand held camera and which show a static subject, portions which track the motion of a moving subject, and portions which show an abrupt event. Methods are presented for identifying such segments, based on motion and / or color analysis of the video footage or based on observations of discontinuities in the video footage following a period of stability.

Description

FIELD OF THE INVENTION[0001]The present invention relates to processes and apparatus for identifying portions of a video footage. Once identified, the portions can be used for multiple purposes. For example, they can be recalled selectively based on their properties, compiled to form a shortened form of the footage, or used as the basis for video editing of the footage such as by using them as a basis for combination with an audio soundtrack.BACKGROUND OF THE INVENTION[0002]Modern devices for recording video footage make it easy to accumulate very large amounts of material which take a very long time to review or process. For example, removing uninteresting footage from within shots taken during a holiday can be a time-consuming process. Similarly, security cameras record vast quantities of footage within which only relatively short sequences containing unusual events are of interest afterwards.[0003]Currently, video editing systems do not provide any form of high level segmentation...
